-## Overview
-
-Custom filament inventory and print tracking system for CubeCraft Creations. Tracks spool consumption, material costs, and per-print COGS across a fleet of 6 FDM printers (5 Bambu Lab + 1 Elegoo Centauri Carbon) + resin printers. Kiosk interface on Raspberry Pi 5 with USB barcode scanner.
-
-**Active refactor in progress:** .NET → Go + React (CUB-110 epic).
-
-## Tech Stack
-
-| Layer | Technology | Notes |
-|-------|-----------|-------|
-| Backend (legacy) | ASP.NET Core 9 + EF Core | Being replaced by Go |
-| Backend (new) | Go 1.24+ | Chi router, pgx (PostgreSQL), gorilla/websocket, paho.mqtt.golang |
-| Frontend (legacy) | Angular 17+ | Being replaced by React |
-| Frontend (new) | React 18 + TypeScript + Tailwind CSS | Vite |
-| Database | PostgreSQL 16+ | snake_case naming |
-| Real-time | SSE (Server-Sent Events) | Replaces SignalR |
-| Printer integrations | Moonraker REST + WebSocket, MQTT TLS | Elegoo/Klipper + Bambu Lab |
-| CI/CD | Gitea Actions | `.gitea/workflows/dev.yml` |
-| Deployment | Docker/Compose, Pi 5 kiosk | |
-
-## Key Design Decisions
-
-1. **Custom system over Spoolman** — Full control over data model and integrations
-2. **MaterialFinish required** on every spool; default is "Basic"
-3. **MaterialModifier is optional**
-4. **Grams derived from:** `mm_extruded × filament_cross_section_area × material_density`
-5. **Push over poll** — SSE + MQTT preferred; Moonraker polling is fallback
-6. **Snake_case** for all PostgreSQL identifiers

-## Known Limitations
-
- Go rewrite is in progress — backend `internal/` is new Go code, but legacy .NET code still serves endpoints
- Kiosk deployment not finalized (CUB-114)
- Smart intake workflow is designed but not implemented
- MQTT Bambu Lab integration is partially complete (CUB-117)

+# Pi 5 Kiosk Setup — Extrudex (Go + React)
+
+## Prerequisites
+
+- Raspberry Pi 5 (4 GB or 8 GB)
+- MicroSD card (32 GB minimum, Class 10+)
+- HDMI touchscreen display
+- USB barcode scanner (HID keyboard mode)
+- Power supply (27W USB-C recommended)
+
+## One-Line Setup
+
+```bash
+# 1. Install Raspberry Pi OS (64-bit, Desktop)
+# 2. Enable SSH and VNC
+# 3. Run the automated bootstrap
+curl -sSL https://raw.githubusercontent.com/CubeCraft-Creations/Extrudex/dev/scripts/pi-bootstrap.sh | bash
+```
+
+Or follow the manual steps below.
+
+## Manual Setup
+
+### 1. Install Docker
+
+```bash
+curl -fsSL https://get.docker.com | sh
+sudo usermod -aG docker pi
+```
+
+Log out and back in for group changes to take effect.
+
+### 2. Clone and deploy
+
+```bash
+cd /home/pi
+git clone https://code.cubecraftcreations.com/CubeCraft-Creations/Extrudex.git
+cd Extrudex
+git checkout dev
+
+# Run the deploy script
+chmod +x deploy.sh
+./deploy.sh
+```
+
+### 3. Verify services
+
+```bash
+docker compose -f docker-compose.dev.yml ps
+# All three services should be "Up"
+```
+
+Check the health endpoint:
+```bash
+curl http://localhost:5080/health
+# Expected: {"status":"ok","db_connected":true,"timestamp":"..."}
+```
+
+### 4. Configure kiosk auto-start
+
+```bash
+# Enable the Docker stack service (starts on boot)
+sudo cp systemd/extrudex.service /etc/systemd/system/
+sudo systemctl daemon-reload
+sudo systemctl enable extrudex.service
+
+# Enable the kiosk service (starts Chromium after Docker stack)
+sudo cp systemd/extrudex-kiosk.service /etc/systemd/system/
+sudo systemctl daemon-reload
+sudo systemctl enable extrudex-kiosk.service
+```
+
+### 5. Configure display server
+
+For Pi 5, Raspberry Pi OS uses Wayland by default. If you encounter
+X11-specific issues, switch to X11 in raspi-config (Advanced Options →
+Resolution → X11).
+
+The kiosk service supports both Wayland and X11 display servers.
+
+### 6. Touchscreen calibration (if needed)
+
+```bash
+# Install calibration tools
+sudo apt install -y xinput-calibrator
+
+# Run calibration, note the device ID and parameters
+xinput_calibrator
+```
+
+Add the calibration to `~/.config/labwc/labwc.conf` or `/etc/X11/xorg.conf.d/`
+as appropriate for your display server.
+
+## USB Barcode Scanner
+
+The USB barcode scanner works as a HID keyboard device — it types scanned
+codes followed by an Enter keypress. No driver configuration is needed.
+
+On the React frontend, the search input auto-focuses on page load and
+will capture barcode input immediately. After a touch on another element,
+tap the search field again to re-focus.
+
+## Auto-Refresh on Wake
+
+The React app polls the SSE endpoint every 30 seconds for real-time
+updates. When the Pi wakes from sleep, the next poll will immediately
+sync the UI.
+
+The kiosk service has `Restart=always` and `RestartSec=10`, so Chromium
+will restart within 10 seconds of any crash or power cycle.
+
+## Touch Gestures
+
+Chromium is launched with `--touch-events=enabled` and `--enable-pinch`
+for native touch gesture support:
+- **Tap** — click/submit
+- **Two-finger scroll** — page scrolling
+- **Pinch** — zoom (disabled in kiosk mode by default; enable if needed)
+
+## Troubleshooting
+
+### Services not starting
+```bash
+sudo systemctl status extrudex
+sudo systemctl status extrudex-kiosk
+docker compose -f docker-compose.dev.yml logs
+```
+
+### Kiosk shows blank page
+- Ensure Docker stack is running: `docker compose ps`
+- Check nginx is serving the React build: `curl http://localhost:5081`
+- Check Chromium logs: `journalctl -u extrudex-kiosk -n 50`
+
+### Barcode not working
+- Verify scanner is in HID keyboard mode (most USB scanners default to this)
+- Open a text field and scan — you should see digits appear
+- Check with `dmesg | grep -i usb` for device enumeration
+
+### PostgreSQL connection refused
+```bash
+docker compose -f docker-compose.dev.yml restart extrudex-db
+# Wait 15 seconds, then check health
+curl http://localhost:5080/health
+```
